R help - May 2001 - Passing a workspace file as argument

What is the best way (if possible) to pass the name of a workspace file to R 
when it starts so it is loaded instead of .RData ?

I would like to know this for Linux and windows version. For windows I would 
like to associate the .RData extension so doubleclicking the file starts R 
and loads it.

Thanks

Why do you want to do that?  R loads the .Rdata in the working directory,
the directory from which it is started, so just cd and then launch R.

Then please submit a patch for that. (You could probably do this via a .bat
file.)  Drag-and-drop to a Desktop icon might be nice while you are at it,
too.

Hi!
I needed different .RData files for different computers linked via nfs
in
order not to overwrite configurations. I did the following:

".First" <-  function ()
{
  image <-
paste(".RData.",Sys.getenv("HOSTNAME"),sep="")
  print("restoring session <",image,"> ...")
  load(image,globalenv())
  if (interactive()) options(error=quote(dump.frames())) 
  else options(error=quote({dump.frames(to.file=TRUE); q()})) 
  options(warn=1)
  gc()
}

If you run several programs in parallel on many different machines with
one home
directory it might be very useful.

If what you want to do is to load functions that have been saved in
another workspace, there is a Q&D workaround for this in "Kickstarting
R", a new version of which should be appearing as soon as I get to work.
